What goes in a Construction Traffic Management Plan
A Construction Traffic Management Plan is judged by the highway engineer discharging the condition, not by a planning officer. Here is what each section has to contain and where submissions usually come back.
A Construction Traffic Management Plan is almost always discharged rather than determined, which changes how you should write it. The highway engineer reading it wants to know how many lorries arrive on the worst day, where they turn, how the wheels get cleaned and who answers the phone when a resident rings at 7am. Answer those four questions precisely and the discharge usually goes through at the first attempt.
Most plans fail because they describe good intentions rather than specified arrangements.
The condition wording that triggers the plan
Read the condition before you write anything, because its wording defines the scope. A typical condition, to be discharged before work starts, asks for a plan covering vehicle routing, parking for operatives, wheel cleaning, storage of plant and materials, and hours of delivery, to be submitted to and approved in writing by the local planning authority.
That list is the contents page. Officers assess discharge submissions against the condition text, not against a generic industry template, so anything the condition names has to appear under a recognisable heading.
Conditions of that kind carry a further procedural layer. Under section 100ZA of the Town and Country Planning Act 1990, an authority cannot impose a condition that must be discharged before development starts without the applicant's written agreement, obtained through the process in the Pre-commencement Conditions Regulations 2018. If the wording is unworkable, the time to say so is during that consultation rather than eighteen months later.
Conditions also have to meet the six tests in national policy: necessary, relevant to planning, relevant to the development, enforceable, precise and reasonable in all other respects. A condition demanding a traffic plan for a two-storey rear extension fails at least two of them.
A Construction Traffic Management Plan is a narrower document than a Construction Management Plan. Traffic, access and the highway are its subject. Dust, noise, waste and working hours belong in the wider Construction Management Plan, and mixing the two makes both harder to approve. Waste arisings sit in a Site Waste Management Plan again, not here.
Site access, routing and swept paths
Start with a drawing, not a paragraph. The plan needs a site access layout at 1:200 or 1:500 showing the construction entrance, gates, visibility at the egress, any temporary crossover and the hoardline.
Routing is a separate drawing at 1:10,000 or similar, showing the approved lorry route from the strategic or primary road network to the site. Name the roads. A route described as "via the main road network" tells the engineer nothing and will come back.
Swept path analysis is what converts intention into evidence. Track the largest vehicle that will actually attend, typically a 16.5m articulated vehicle for major deliveries, an 11.6m rigid for concrete and a 12.5m tipper for muck away, through the entrance, around any turning head and back out in forward gear. Reversing onto or off a public highway is the single most common reason a highway officer objects.
Where the route passes a school, a narrow bridge, a weight restriction or an unsuitable junction, say so and set out the prohibition. A plan that pretends the constraint does not exist loses credibility for everything else in it.
Vehicle numbers by phase and hour
Give numbers. A table of two-way movements by construction phase, with the peak day identified, is the part of the plan the highway authority actually uses.
| Phase | Typical duration | Peak daily two-way HGV movements | Dominant vehicle |
|---|---|---|---|
| Demolition and site clearance | 4 to 8 weeks | Highest of the programme | Tipper and grab |
| Groundworks and substructure | 8 to 16 weeks | High | Tipper, concrete mixer |
| Superstructure | 12 to 30 weeks | Moderate | Flatbed, crane deliveries |
| Envelope and fit out | 20 to 40 weeks | Low but frequent | Rigid and transit |
| External works | 4 to 10 weeks | Low | Tipper, plant low loader |
The durations above are indicative and should be replaced with the contractor's own programme. What matters to the officer is that the peak is identified, that it is tied to a phase and that deliveries outside agreed hours are excluded by a booking system rather than by hope.
Delivery booking is worth a short paragraph of its own. A slot system with a fifteen or twenty minute window, a holding arrangement off the public highway and a named contact for hauliers turns a theoretical restriction into something enforceable.
Wheel washing and highway cleanliness
Depositing mud on the highway is an offence under the Highways Act 1980, and authorities do prosecute where a site is persistently dirty. The plan should specify the equipment rather than promise cleanliness.
Specify the type, whether that is a drive-through wheel wash with recirculating water, a spray bar over a rumble grid, or a jet wash bay with an interceptor. State the position on the layout drawing. State the length of hardstanding between the wash and the exit, because a vehicle that drives twenty metres over bare ground after washing arrives at the gate as dirty as it started.
Then set out the backup: a road sweeper on call, a stated frequency during muck away, a manual inspection at the end of each working day and a record kept on site. Interceptors and any discharge from the wash need to be dealt with properly, and on a larger site that means a trade effluent consent from the sewerage undertaker.
Parking for operatives and deliveries
Construction parking causes more complaints than construction lorries. Count the workforce by phase and say where each vehicle goes.
On a constrained urban site the honest answer is often that on-site parking is impossible during the substructure phase. If so, the plan should describe the alternative: a travel plan for operatives, a contribution to a local car park, a minibus from a remote compound, or restricted parking permits. An unexplained gap invites a condition you cannot comply with.
Loading and unloading must happen within the site boundary wherever the geometry allows. Where a temporary road closure or a suspension of parking bays is needed, name the traffic authority procedure and the notice period, because those consents sit outside the planning permission.
Abnormal loads and crane operations
Anything exceeding the normal construction and use limits needs notification under the special types regime, and on the strategic road network that runs through the Electronic Service Delivery for Abnormal Loads system operated by National Highways. Police and bridge authority notice periods vary with the load class, so the plan should identify the expected abnormal movements at the outset rather than treating them as an operational detail.
Crane operations need their own section. Cover the crane type and position, the oversail area, whether any jib passes over adjoining land or the highway, and the third-party agreements that follow. Oversailing a neighbour's airspace without consent is a trespass regardless of what the planning permission says.
Where the site sits within an aerodrome safeguarding zone, tall cranes trigger consultation with the airport operator and, above the relevant heights, notification arrangements for aviation warning lighting. Check the safeguarding maps early, because crane height often drives the construction methodology.
An illustrative example
A 42-unit scheme on a former garage site with a single access onto a B road. The approved plan identified a peak of 28 two-way HGV movements during a six-week muck away phase, restricted arrivals to 09:30 to 15:30 outside school peaks, specified a drive-through wheel wash with 25m of hardstanding to the gate, banned reversing onto the B road by providing an internal turning head tracked for a 16.5m vehicle, and named a site manager with a monitored phone number displayed on the hoarding. This example is illustrative rather than drawn from a specific case.
Complaints procedure and named contact
The last section is the one residents read. It should give a named role, a telephone number monitored during working hours, an out-of-hours number and a target response time.
Set out how complaints are logged, how the log is made available to the authority on request, and what happens when a complaint is upheld. Registration with a recognised considerate contractor scheme is worth stating where it applies, though it is not a substitute for the procedure.
Working hours belong here too, even though they usually sit in a separate condition. Standard restrictions of 08:00 to 18:00 on weekdays and 08:00 to 13:00 on Saturdays, with no working on Sundays or bank holidays, are common but not universal, so quote the actual condition.
And put the plan's review mechanism in writing. A statement that the plan will be updated and resubmitted if the contractor, the programme or the access arrangements change is what stops the discharge becoming stale halfway through the build.

Frequently asked questions
Is a Construction Traffic Management Plan the same as a Construction Management Plan?
No. The traffic plan deals with the highway: routing, access, swept paths, vehicle numbers, parking, wheel washing and abnormal loads. The wider construction management plan covers dust, noise, working hours, waste, lighting and site security. Some authorities ask for one combined document and some for both. Read the condition wording, because that defines which one you are being asked to produce.
When does the plan have to be submitted?
Usually before development starts, because the condition bites before work starts. Allow eight weeks between submission and the intended start on site, since the planning authority consults the highway authority and a discharge decision has a statutory period. Starting work before the plan is approved breaches the condition and can make the whole development unlawful in some circumstances.
What size vehicle should the swept path analysis use?
Track the largest vehicle that will attend the site in practice. For most residential schemes that means a 16.5 metre articulated vehicle for major deliveries, an 11.6 metre rigid for concrete and refuse, and a tipper for muck away. Show entry, any internal turning movement and exit in forward gear, since reversing onto a public highway attracts an objection almost automatically.
Do I need to specify a particular wheel wash?
Yes, name the type and show it on the layout drawing. A drive-through wash with recirculating water, a spray bar over a rumble grid, or a jet wash bay with an interceptor are all acceptable in the right setting. State the length of hardstanding between the wash and the site exit, and set out the road sweeper arrangement as a backup.
Who should be named as the contact for complaints?
Name a role rather than an individual, such as the site manager, and give a number monitored during working hours plus an out-of-hours number. Say how complaints are logged, what response time applies and that the log will be available to the authority on request. Display the same details on the hoarding so residents do not have to search for them.
